The lake itself is wonderful for swimming and the Aqua park looks a lot of fun. There’s plenty for everyone to do including paddle boarding and of course the go-carts !
The staff are very attentive and will happily help with any of your needs.
I was happy to find a vegan sandwich in the restaurant which many places don’t have.
Will definitely be back for more.
All the children had an amazing time from start to finish. They went on the aqua park first which they all throughly enjoyed ,one child needed help but with a quick shout to the life guard they had help immediately. They were all given very clear instructions by the staff before going on, there is a lot of mixed ages together which I was a little worried about but once on they are all spread out and it was fine. They all then went on the go karts! Most of the children were a little worried to try but the staff were brilliant helped with anything they needed and answered any questions they had and put them at ease.
It was an absolutely brilliant day had by all. One thing I will say is maybe there needs better signage everywhere as if it is your first time coming you might get a little confused on where to go for things.
I will definitely be back again real soon
